Definitions

  • the present invention relates to a web splicing method and a web splicing apparatus.
  • Japanese Laid-Open Patent Publication No. 10-45290 discloses an automatic web splicing apparatus for splicing a web with another web while maintaining a constant tension on the web.
  • the web velocity is detected by a line pulse generator on the output side of the automatic splicing apparatus to calculate the diameter of a roll of web based on the web velocity, or the like, and the braking force is controlled based on the diameter of the roll, or the like, thereby maintaining a constant torque.
  • maintaining a constant line velocity on the output side of the automatic splicing apparatus is not taken into consideration.
  • a splicing method of the present invention includes the steps of: spinning a first roll of web to feed out a first web so as to store a predetermined length of the first web in an accumulator; stopping the spinning of the first roll; connecting a second web fed out from a second roll of web to the first web; cutting off the first web at a position between a point at which the second web is connected to the first web and the first roll; spinning the second roll to feed out the second web after the first web is cut off; obtaining a diameter of the second roll based on a state of the accumulator; and controlling a circumferential velocity of the second roll based on the obtained diameter.
  • the circumferential velocity of the second roll i.e., a flow velocity of the second web to be supplied to the accumulator
  • the diameter of the second roll which is connected to an end of the first web. Therefore, a tension on the first and second webs being fed to the accumulator is kept at a predetermined value irrespective of the diameter of the second roll, and the first and second webs can be output from the accumulator at a constant velocity, even during the web splicing operation.
  • the diameter of the second roll may be obtained by directly measuring the diameter of the second roll, it requires an expensive measurement device.
  • the diameter of the second roll may be calculated from a position of a movable roller associated with the accumulator, as in the following splicing apparatus.
  • a splicing apparatus of the present invention includes: a first driver capable of spinning a first roll of web; a second driver capable of spinning a second roll of web; a splicer for connecting a second web fed out from the second roll to a first web fed out from the first roll, and cutting off the first web; an accumulator provided downstream of the splicer capable of storing the first web or the second web; a sensor capable of measuring a position of a movable roller; and a controller for controlling a rotational speed of the first driver and that of the second driver.
  • the controller is operable to calculate the diameter of the second roll based on a positional change of the movable roller, information regarding an angular velocity of the second driver and a web flow velocity at a position downstream of the accumulator.
  • the controller is further operable to calculate an appropriate rotational speed of the second driver based on the diameter of the second roll.
  • the controller is yet further operable to control the connecting and cutting operation of the splicer while controlling the second driver according to the appropriate rotational speed.
  • a change in an amount of the web stored in the accumulator can be determined from a positional change of the movable roller. Specifically, when the first or second driver is moving away from a fixed roller associated with the accumulator, the velocity at which the web is fed out from the first or second respective roll is greater than the velocity at which the web is output from the accumulator (e.g., a line velocity), thereby increasing the amount of the web stored in the accumulator. On the other hand, when the movable roller is moving toward the fixed roller, the velocity at which the web is fed out from the first or second roll is less than the line velocity, thereby decreasing the amount of the web stored in the accumulator.
  • the amount of the web stored in the accumulator increases, whereas when the velocity at which the web is fed out from the first or second roll is smaller than the line velocity, the amount of the web stored in the accumulator decreases.
  • the velocity at which the web is fed out from the respective roll is equal to the diameter of the roll multiplied by the angular velocity of the respective driver, whereby the diameter of the roll can be known from the positional change of the movable roller, the line velocity and the angular velocity.
  • the term “information regarding the angular velocity of a driver” is not limited to the angular velocity of a motor associated with the roll of web, but may also be, for example, the angular velocity of a shaft associated with the roll of web.
  • the position of the movable roller may be measured by detecting the movable roller itself, but may alternatively be measured by detecting a position of a frame that rotatably supports the movable roller.
  • FIG. 1 is a schematic of a web splicing apparatus according to one embodiment of the present invention.
  • FIG. 2 is a diagram illustrating a principle of obtaining the diameter of a roll.
  • FIG. 3 is a schematic illustrating a variation of an accumulator.

  • the first driver 1 A and the second driver 1 B may be driven separately by independent motors (not shown), or by a single motor while switching the connection therebetween by a clutch (not shown), or the like.
  • the web W is moving at a velocity V O by a driver (not shown).
  • a driver for example, when the driver is connected to a motor, a predetermined signal may be issued for each turn of the motor, based on which the velocity V O can be known.
  • a motor may be a servo motor, or the motor that be vector-controlled.
  • the velocity V O can be known by measuring an amount of rotation of the driver itself with an encoder.
  • the splicer 3 includes a connection section 30 for connecting together the first web Wa fed from the first roll A and the second web Wb fed from the second roll B while lapping the first web and the second web over each other.
  • the connection section 30 may sandwich the first web Wa and the second web Wb and connect them together by a heat seal or an ultrasonic seal.
  • an adhesive or a double-sided adhesive tape may be applied on one side of the second web Wb before the second web Wb is inserted into the connection section 30 .
  • one of the webs W (the first web Wa or the second web Wb) is cut off at a position between the splicer 3 and the roll A (B).
  • the connection section 30 connects the first web Wa and the second web Wb together, and then one of the webs W (the respective first web Wa or the second web Wb) is cut off at a position upstream of the connection section 30 with a cutter 31 such as a heat cutter, an ultrasonic cutter, a laser cutter, or the like.
  • the cutter 31 for cutting the web W may be a cutting tool protruding from the splicer 3 toward the web W. After the first web Wa or the second web Wb is cut off, the connection section 30 opens up to release the webs Wa and Wb. In this way, the web W flowing after the splicer 3 is switched between the respective first web Wa and the second web Wb.

  • the tension on the web W can be kept at a predetermined value.
  • rollers 42 and 43 are small. Therefore, it is preferred that at least the movable rollers 42 and the fixed rollers 43 are made of a light-weight material such as an aluminum alloy, a resin, a carbon graphite, or the like. Note that it is more preferred that all the rollers of the splicing apparatus around which the web W is passed are made of a light-weight material.

  • the controller 5 separately controls the rotational speed of each motor.
  • the present apparatus alternately transfers the webs Wa and Wb while connecting them together as described above. For the purpose of illustration, it is assumed in the following description that the second web Wb is connected to the first web Wa.
  • the accumulator 4 stores an average amount of the first web Wa (or the second web Wb) between the maximum amount and the minimum amount of the web Wa that can be stored therein, so that fluctuations in the amount of the first web Wa supplied can be optimally accommodated.
  • the controller 5 increases the rotational speed of the first driver 1 A so that a predetermined amount of the first web Wa that is greater than the above-mentioned average amount is stored in the accumulator 4 .

  • the state of the accumulator changes according to the amount of a web supplied into the accumulator and the amount of a web output from the accumulator, after the webs are spliced together and the appropriate driver starts spinning.
  • V I (t) is the supply velocity at which the web is supplied to the accumulator
  • V O (t) is the line or output velocity at which the web is output from the accumulator (normally, the output velocity is equal to the line velocity, and is thus constant).
  • the relationship between the position P and the amount X may be stored in the controller 5 as a table.
  • the amount X may be geometrically calculated from the position P by the controller 5 .
  • the relationship between the position P and the amount X may be stored in the controller 5 as a table.

  • R IN is the radius of the roll B (A) upon completion of a web splicing operation
  • T W is the thickness of the web W
  • N is a number of turns the roll B (A) has been spun.
  • the diameter of the roll B can be obtained from the position P of the movable rollers 42 while increasing the velocity at which the web W is fed, although this will fluctuate the amount of the web W stored in the accumulator 4 .
  • the position of the movable rollers is detected, and the diameter of the roll A or B is obtained based on the positional change of the movable rollers 42 , i.e., the velocity at which the movable rollers are moved, whereby it is possible to obtain the diameter of the roll even during a web splicing operation. Therefore, the speed of the driver 1 A or 1 B can be controlled at an appropriate value based on the diameter of the roll A or B, whereby it is possible to perform a web splicing operation while maintaining a predetermined tension on the web W being fed out and without changing the line velocity V O of the web downstream of the accumulator 4 after the web splicing operation.
  • the positional change of the movable rollers 42 is much easier to detect than the velocity of the web W. Furthermore, for any splicing apparatus, it is advantageous to detect the position P of the movable rollers 42 . Therefore, by using the position P of the movable rollers 42 , it is possible to avoid the provision of a new sensor, thereby reducing the cost.
